# MODEL\_LBL

> This page is not the authoritative source for design information. The official [IS3720 datasheet](https://www.inacks.com/is3720) published on [www.inacks.com](http://www.inacks.com) is the authoritative reference: always consult it for the latest information.

The MODEL\_LBL register block contains a text description for the device model number (MODEL\_NUM).

This text appears on the lighting operator’s console, it is for informational purposes only and does not affect RDM or DMX device operation.

This register is filled with text string and corresponds to the RDM parameter 0x0080 DEVICE\_MODEL\_DESCRIPTION.

This register composed by a block of 32 8-bit registers. Register address 563 is the high byte (first character) and register address 594 is the low byte (last character).

Allowed values for this register are any readable ASCII characters. The null character (value 0) is also valid and may be used for string termination.

This register block can be read and written via I2C, and read via RDM.

This is a non-volatile register block. On each power-up, it loads its last stored value. Writing the same content to non-volatile memory that it previously held does not trigger a write cycle; therefore, it is safe to write to this register at every startup of your firmware.
